Question about Canon EOS 40D Digital Camera

1 Answer

Canon 40d won't turn on, LCD is blank.

Took 10 pics today then charged the battery and when I put it back in the camera won't turn on.  I put another battery in from a 50d and still a no go.  Is there a reset button somewhere on the camera?  Thanks

There are several different things that can cause the camera to not start up. Refer to your user manual to check each of these items. If you don't have your user manual, you can download it here.

1) The battery is not properly installed in the camera. (p.26)
2) Make sure the battery compartment cover is closed. (p.26)
3) Make sure the CF card slot cover is closed. (p.28)

In addition, the battery may not have been properly recharged. Double check that the charger is plugged into a working outlet, and double check that it shows that the battery is fully charged.

If none of these fix the problem then you have a defective camera - one of the switches for the battery compartment or the CF card slot cover may be not properly indicating that the door is closed. If that's the case, you need to either return it to the place of purchase as defective, or send it in to Canon for warranty repair.

FORGOT PASSWORD IN RESTRICTED MODE CANON 40D


Try doing a "hard reset" to clear all the camera settings to factory specs:

  1. To reset the camera, remove main battery and back-up battery (Backup battery compartment says CR2016 3V on the wall of the compartment is a little tray that slides out)
  2. Turn the camera off/on switch to ON
  3. Wait 10 sec turn OFF
  4. Replace batteries.

I have a brand new Nikon D3100. The battery was fully charged and placed in the camera. I took about 4 photos, and then turned the camera off. When I turned it back on the battery wasn't working to...


The solution to your problem is simple, Kathrynbax.


The battery never comes in fully charged. It's always charged only so you may be able to check if your camera is working. I suggest, you take out your battery and put it to charge for exactly 90 minutes as the manual says. Then I'm sure you won't face any such problems.


Hope this solves your problem.

Good day!

Camera won't switch on, put new batteries in it, took a photo to test, since then it won't switch on.


If you were able to take one shot before the camera packed up it can be that the battery does not have charge on it and so after the first shot it has drained the battery. So check out the charge on it or repeat charging to test once again.
Other wise it can be that the camera control unit is faulty. Try and reset by removing battery for a while and trying once again.

It is brand new I charged the battery all day and put it in the camera and it wont turn on


Try to use non-rechargeable LR6 batteries.
If it still does not work the camera needs a repair.

My 40d does not turn on, battery was fully charged, charger showed full light, put battery in, and camera does not turn on. Help!


You may need to remove the battery and use a screwdriver to scratch the battery contact point in the camera. It may have been coated or corroded.

Canon 40d-pressing the shutter seems to short out the camera.


I recommend that you remove both batteries for ten minutes to get a full reset. you spoke of the main battery. When you open the battery compartment, look at the lower right toward the camera with the LCD facing you.
It is a little hard to see, but will say CR2016 3V. Stick your fingernail under the lip and just pull it out.
As I said I left both batteries out for about 10 minutes.
You will have to re-set the date and time after your done.

Canon 50D failure to turn on


Did you figure this out? I would send it back asap so your warranty can cover the problem. Also run over to Ritz camera or another camera store to figure if they can help. Ask for their Canon expert. I hope this helps.
